| Terminal branch of ECA | maxillary artery |
| Parts of maxillary artery are in relation to | lateral pterygoid muscle |
| Parts 1 and 2 of Maxillary artery are where | part 1-ITF- posterior and medial to mandible and pterygoid Part 2- ITF-superficial to or within lateral pterygoid |
| Part 3(pterygopalatine) of maxillary artery is found where | PPT-within pterygoplatine fossa |
| 5 branches of mandibular part of maxillary artery | Deep auricular Anterior tympanic Middle Meningeal Accessory menigeal Inferior alveolar |
| Deep auricular artery | branch of mandibular of maxillary, goes to EAM and tympanic membrane and TMJ |
| Anterior tympanic artery | Branch of mandibular of maxillary, goes to Internal tympanic membrane |
| Middle meningeal artery | enters cranium via foramen spinosum supplies bone, dura matter, trigeminal gangion, facial nerve |
| Accessory meningeal artery | forament ovale supples muscles of infratemoral fossa and sphenoid bone, mandibular nerve and otic ganglion |
| Inferior aveolar artery | mandible, mandibular teeth, chin, mylohyoid |
| 4 branches of pterygoid part of maxillary | Masseteric deep temporal pterygoid branches buccal artery |
| Masseteric artery | TMJ and masseter |
| Deep temporal artery | temporalis muscle |
| pterygoid branches | pterygoid mm |
| buccal artery | buccinator and oral mucosa |
| 6 Branches of pterygopalatine (part 3) artery of maxillary | posterior superior alveolar infraorbital descending palatine artery of pterygoid canal (vidian) pharyngeal branch sphenopalatine |
| Posterior superior alveolar artery | maxillary molars and gingiva |
| Infraorbital artery | maxiallary canines and incsors |
| Descending palatine artery | mucosa and glands of soft palate |

| 4 branches of V3 | auriculotemporal inferior alveolar lingual buccal |
| Auriculotemporal | auricle, temporal, TMJ, parotid |
| Inferior aveolar | forms inferior dental plexus for mandibular teeth |
| lingual nerve | sensory to anterior 2/3 of tongue |
| buccal nerve | sensory infor from buccal membrane cheek and from molar teeth |
| Otic Ganglion | parasympathetic innervation to parotid gland and salivation |
| Chorda tympani | Off of CN7, runs P to A through inner ear, through ITF, to join lingual nerve; taste to anterior 2/3 tongue |
| Entryway to the pterygoplatine fossa | pterygomaxillary fissure |
| ITF to PP fossa via what | pterygomaxillary fissure |
| From middle cranial fossa to PP fossa | foramen rotundum |
| Orbit to PP fossa via | inferior orbital fissure |
| From nasal cavity to PP fossa | sphenopalatine fossa |
| Contents of PP fossa | 3rd part of maxillary artery venous tributaries of pterygoid plexus maxillary nerve (V2( and branches pterygopalatine ganglion |
